That's the different domain. 5G standards are defined for Licensed, unlicensed as well as non-mobile world (means the core network can support all the different access technologies). CBRS is licensed band, just free to use but you have register.
6GHz is new band opened for unlicensed spectrum. It will mostly be used by next generation WiFi (may be WiFi 6 too). Any other technology can use that band too and 5G standards may enhance to support this band or may define other technology too. Just last month, ITU accepted the DECT (remember cordless phones) technology to be part of 5G ecosystem (5G core will be able to support devices with DECT air interface).
But CBRS band is different and its more about similar to current mobile ecosystem but in private domain.
CBRS cant be used for WiFi or other technology (only 4G in US at this point, most probably 5G in future.. 3GPP defined OFDMA based air interface). 6GHz is unlicensed and mostly will be used by WiFi.
